HERBERT J. L. CHINNECK, 0F BOONE, IOWA, ASSIGNOR TO QUINN WIRE & IRON WORKS,

OF BOONE, IOWA.

GALE WEANER,

Application filed March'22, 1922.

Z '0 (17/ qeilomit may coacem Be it known that I, Hnnmnrr J. L. CHIN- Macn, a citizen of the United States. and resident of Boone, in the county of Boone and State of Iowa, have invented a certain new and useful Calf Weaner, of which the following is a specification.

The object of my invention is to provide a calf weaner of simple, durable and inexpensive construction, which. may be applied to the calf quickly, easily and conveniently and when applied will efficiently serve the purposes of a calf weaner.

More specifically it is my object to provide a device of this class which may be formed complete of two pieces of galvanized sheet metal and maybe formed by dies and formers, and readily and quickly assembled by means of rivets, thereby providing a device of this class which may be made at minimum cost and with a minimum of hand labor.

My invention consists in the construction, arrangement and combination of the various parts of the calf weaner, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 shows a front elevation of a calf weaner embodying my invention, the dotted lines show the two parts of the weaner separated as required for applying it to a calf.

Figure 2 shows a detail perspective view illustrating one of the nostril engaging arms.

Figure 3 shows a detail sectional view on the line 3-3 of Figure 1, illustrating the manner in which the overlapping portions of the calf weaner are locked in position. In this figure the dotted lines show the positions of the parts when they have been unlocked to separate the nostril engaging arms.

Figure shows sectional view on the line 4 -4' of Figure 1. The dotted lines in this figure show the relative positions of the parts when the nostril en aging arms are in their positions spaced apart from each other, and

Figure 5 shows a detail perspective view of one of the cushioning heads for the nostril engaging arms.

Referring to the accompanying drawings, the device is seen to be composed of two parts, each of which comprises a sheet metal body portion having projected from its periphery a series of prongs 11, and also Serial No. 545,827.

having at its upper portion a nostril engaging arm 12 extending upwardly and inwardly and preferably provided with barbs 13 to receive the cushioning head 14. This cushioning head is preferably made of soft rubber with a rounded knob and also a slot into which the arm 12 may be inserted, and when this is done the barbs 13 prevent it from being withdrawn.

At the lower end of each member there is formed a lug 15 which is bent to position across the edge of the opposite member and then inwardly over the surface of the opposite member, the part thereof that extends inwardly over the surface of the opposite member is spaced apart from the opposite member, as clearly shown in the drawings. Each member is also provided near its lower end with a rounded projection 16, formed by cutting a slot in the sheet metal and pressing the material at one side of the slot outwardly. The two members are assembled bymeans of a rivet 17, passed through them near their upper ends. 7

The arrangement of the parts is such that when the two members are in the position shown in Figure 1 by solid lines, the rivet 17 will hold the parts in position with their overlapping central portions lying flat against each other. Each member will have one lug 16 arranged with its straight edge in engagement with the adjacent edge of the opposite member so that the two parts can not be moved relative to each other. However, since both parts are made of galvanized sheet metal the parts that overlap each other may be sprung apart slightly by a twisting motion applied to the sides of the body so that each of the lugs 16 will then ride upon the adjacent surfaces of the other member. This springing or separating movement, however, is limited by the lugs 15.

When the parts are in the position last named, the two nostril engaging members may be widely separated, as shown by dotted lines in Figure 1, then the device is applied to a calf or other animal by simply inserting the cushion members 14 in the animals nostril openings and then moving the nostril engaging arms toward each other until the resiliency of the sheet metal body portions causes them tospring back to their original positions with their straight edges engaging the lugs 16, whereupon the nostril engaging arms are then lockedv in position against outward movement relative to each. other and whereupon the device is permanently and.

firmly secured to the animal and can not be removed except by applying a twisting motion to both of said body portions sufficiently to cause them to ride over the lugs 16, as before explained, and this movement cannot be had by the strains to which such devices are ordinarily subjected when in use;

The device when applied to a calif or other animal will not in any way interfere with its ordinary feeding operations except that in the event that the calf should attempt to obengaging member at the upper end of each of said sheet metal members, one or the members being provided near 1ts lower portlon with a pro ect1on and the opposlte member being provided with a depression to receive the projection, each member being provided at its lower edge with a lug shaped to overlap the adjacent edge of the opposite member and being spacedapart from said opposite member far enough to permit the members to spring apart to a limited extent, and whereby during the pivotal movement of the members in relation to each other said lugs will travel around the concentric edges of the-twomembers for the purposes stated.

2. In a device of the class described, the combination of two members pivotally connected with each other and each formed of sheet metal, each member being provided above its pivotal center with an arm extending upwardly and inwardly and formed with barbs, a nostril engaging member for each of said arms comprising a rounded head, and an elongated body portion, the latter being formed with a slot to receive the arm, and said nostril engaging member being formed of elastic yielding material, whereby it is adapted to co operatewith the barbs to hold it firmly in position.
